The SourceDisksFiles section names the source files used during installation and identifies the source disks that contain the files. In order to allow multi-platform distribution of source files, you can construct a platform-specific SourceDisksFiles section. For example, all Setup functions that use a SourceDisksFiles section will first look for a SourceDisksFiles.mips section on a MIPS platform and only look in a SourceDisksFiles section if the line was not found in SourceDisksFiles.mips. This behavior affects any Setup function that directly or indirectly references a SourceDisksFiles section as part of its processing.
[SourceDisksFiles] filename=disk-number[,subdir][,size] . . .
The following example SourceDisksFiles section identifies a single source file, SRS01.x86, on the disk with the ordinal of 1.
[SourceDisksFiles] SRS01.x86 = 1
